This threshold is set for 3.3V logic systems where the supervisor must trip before the downstream devices enter an undefined state. The reset output is open-drain, so it can be wire-ORed with other reset sources on the same bus. ## 150ms reset timeout — sizing for power-up settling For a typical MCU with a 10ms power-up delay, this margin is comfortable; for a larger system with multiple rails and a PLL, the 150ms window may need to be verified against the slowest rail's rise time.","metaTitle":"MCP120T-315I/SN Simple Reset/Power-On Reset","metaDescription":"Microchip MCP120T-315I/SN simple reset IC, active-low open-drain output, 150ms min timeout, 3.075V threshold, -40°C to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"150ms Minimum","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.075V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.72","priceTiers":[{"qty":1,"price":"$0.72000","currency":"USD"},{"qty":25,"price":"$0.59360","currency":"USD"},{"qty":100,"price":"$0.54060","currency":"USD"},{"qty":3300,"price":"$0.54060","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/441d4b733858cb14ab031f79c91ff691.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MCP120T-315I%2FSN/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of MCP120T-315I/SN?","answer":"The reset timeout is 150ms minimum.
